General description

Microtubule-associated protein 2 (MAP2) is a neuronal protein. It belongs to the MAP2/Tau family. This gene is located to human chromosome 2q34-q35. MAP2 is present in neurons. MAP2 is the major microtubule-associated protein of brain tissue. There are three forms of MAP2; two are similarly sized with apparent molecular weights of 280kDa (MAP2a and MAP2b) and the third with a lower molecular weight of 70kDa (MAP2c).

Specificity

Reacts with all known forms of MAP2, namely MAP2a, MAP2b and MAP2c. Does not cross-react with other MAPs or tubulin. By immunohistochemical staining of formalin-fixed, paraffin-embedded brain tissue, the antibody shows selective labeling of dendritic trees throughout the brain.

Immunogen

rat brain microtubule-associated proteins (MAPs).

Application

Monoclonal Anti-MAP2 (2a+2b) antibody has been used in immunohistochemistry, immunostaining and western blotting.

Biochem/physiol Actions

Microtubule-associated protein 2 (MAP2) interacts with microtubules to maintain the structure of dendrites. It plays a major role in supporting the actin cytoskeleton in spines, binding and nucleating filamentous actin (f-actin) to modulate spine morphology.

Physical form

Supplied as ascites fluid with 15 mM sodium azide as a preservative.

Storage and Stability

For continuous use, store at 2-8 °C for up to one month. For extended storage, the solution may be frozen in working aliquots. Repeated freezing and thawing, or storage in "frost-free" freezers, is not recommended. If slight turbidity occurs upon prolonged storage, clarify the solution by centrifugation before use.
